该X探伤机启动时，通过控制器1发出启动命令，此时控制器1中的延时控制电路开始工作，在延时期间内，操作人员可迅速离开操作现场，防止被探伤机启动时发出的X射线伤害，该延时控制电路包括稳压滤波电路、第一延时控制电路、第二延时控制电路和控制执行电路，其中第一集成电路U1和第二集成电路U2分别与外接阻容元件组成两个单稳态触发器。平时在未按第一按钮S1-a和第二按钮Sl-b时，第一集成电路U1和第二集成电路U2的输出端均输出低电平。按下第一按钮S1-a和第二按钮Sl-b时，第一按钮S1-a和第二按钮Sl-b接通，使第一集成电路U1和第二集成电路U2的触发点端变为低电平，单稳态触发器翻转而进入暂态，输出端输出高电平，第一继电器线圈K1-2和第二继电器线圈K2-2均通电吸合，第一发光二极管LED1和第一发光二极管LED1均点亮，第一继电器开关K1-1断开，第二继电器开关K2-1接通；与此同时，第一电容C1和第三电容C3分别通过第二电阻R2和第五电阻R5充电。当第一电容C1两端电压充至8V(约30s)时，第一集成电路U1内电路翻转，由暂态恢复为稳态，第一集成电路U1的输出端变为低电平，第一发光二极管LED1熄灭，第一继电器线圈K1-2释放，第一继电器开关K1-1接通，第三继电器线圈K3-2通电吸合，第三继电器开关K3-1接通(相当于按下第三开关S2)，曝光电路通电 工作。再经8s的延时，第二集成电路U2也翻转为稳态，其输出端变为低电平，使第二发光二极管LED2熄灭，第二继电器线圈K2-2和第三继电器线圈K3-2释放，一次曝光结束。该电路中通过第二电阻R2和第五电阻R5分别对第一电容C1和第三电容C3充电的时间进行控制，对探伤机进行延时控制，再利用第一集成电路U1和第二集成电路U2由暂态恢复为稳态的时间差，实现了对曝光结束时间进行控制，保证了工作人员对整个探伤过程的精确把控，提高了该探伤机的可靠性和安全性。
当探伤机运行时，壳体2内的温控装置也处于运行状态，由引水泵5引入蓄水箱9中的溶液，通过连接管6导入到壳体2的内部，带走壳体2内的高温热量，最后溶液经过导入管6返回流入到蓄水箱9中，溶液如此反复循环流动，以此限制X射线探伤机内部温度过高，从而保证了X射线探伤机的寿命。
与现有技术相比，该用于工业生产的X射线探伤机通过控制器1中的延时控制电路，使启动命令在一定时间后运行，防止启动时X射线对工作人员的伤害，保证了工作人员对整个探伤过程的精确把控，提高了该探伤机的可靠性和安全性，同时，通过制冷装置中引水泵5的工作，带动水流在探伤机内部循环流动，带走热量的同时限制了探伤机内的温度，从而延长了探伤机的寿命。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
